🚀 Top Rated Google Sheets & Apps Script developer. I build automations, dashboards, and custom tools that turn messy spreadsheets into systems your team can actually trust — and I've cut clients' manual data work by up to 80%. If your business runs on Google Sheets (or you're escaping Excel), I make it run by itself. I'm Nazar — a Top Rated Google Sheets, Google Apps Script, and Python developer specializing in spreadsheet automation, web automation, data scraping, and reporting in Tableau and Looker Studio (Google Data Studio). Whether you need a complex Google Apps Script workflow, a live Tableau dashboard, or a Looker Studio report pulling from Google Sheets and SQL, I deliver clean, scalable solutions that save hours and drive better decisions. WHAT I DO - Google Apps Script automation: auto-send emails, generate PDF reports, sync data on a schedule, and connect Google Sheets to third-party APIs (OpenAI, Slack, CRMs, payment tools). - Google Sheets development: inventory systems, CRMs, quoting and estimating calculators, and financial models built right inside Google Sheets. - Tableau & Looker Studio dashboards: interactive Tableau and Looker Studio (Google Data Studio) dashboards pulling from Google Sheets, SQL, and APIs, so you decide on live data. - Web automation & data scraping: Google Apps Script and Python scrapers that fetch, clean, and pipe web data straight into Google Sheets on autopilot. - Excel to Google Sheets migration: complex Excel logic rebuilt as clean, cloud-based Google Sheets workflows. - Fixing & optimizing: slow or broken Google Sheets and buggy Apps Script debugged, sped up, and made reliable. - Formulas & data cleaning: advanced Google Sheets formulas, pivot tables, and structured, error-free data that performs fast. REAL RESULTS (what I did then what the client got) - Built a Google Apps Script automation that replaced hours of copy-paste, so the client got 80%+ less manual data entry and a team that scaled without new hires. - Designed Tableau and Looker Studio dashboards on top of their Google Sheets, so the client got a 20% jump in operational efficiency by exposing bottlenecks they couldn't see before. - Wired real-time PPC reporting into a Looker Studio (Google Data Studio) dashboard, so the client got 30% better ad ROI. - Built an Apps Script and Python data scraping pipeline, so the client got live market data flowing into Google Sheets every day with zero manual work. - Automated weekly reporting with Google Apps Script feeding a Looker Studio dashboard, so the client got their numbers in minutes instead of a full day. - Connected Google Sheets to the OpenAI and Slack APIs with Apps Script, so the client got AI-enriched data and instant team alerts without lifting a finger. - Rebuilt a tangled Excel model as a Google Sheets system with Apps Script, so the client got reporting that was faster, shareable, and finally accurate. WHO I WORK WITH Founders, operations teams, marketing agencies, ecommerce stores, and finance teams who live in Google Sheets and need Apps Script automation, Tableau or Looker Studio dashboards, or web data scraping that just works — whether it's a one-off fix or an ongoing build. RECENT PROJECTS Google Sheets inventory systems; automated CRMs in Google Apps Script; Tableau & Looker Studio (Google Data Studio) reporting; quoting and estimating calculators; Apps Script and Python web scrapers and data fetchers; Google Sheets API connectors (OpenAI, Slack, and more); and end-to-end web automation workflows. TOOLS Google Sheets, Google Apps Script, JavaScript, Python, Tableau, Looker Studio (Google Data Studio), SQL, Microsoft Excel, Google Workspace, and the Google Sheets API. WHY ME Top Rated, with a track record of clean, scalable code and clear communication. I don't just write a quick Apps Script and disappear — I build Google Sheets and Tableau/Looker Studio solutions you don't have to babysit, and I document everything so your team can run with it. HOW I WORK I scope the real problem first, then build the Google Sheets automation, Apps Script workflow, web scraper, or Tableau/Looker Studio dashboard around it. Most projects start with a quick call so I understand your data before I touch it, and I keep you updated at every step, with fast replies and clear timelines.

I build production-grade Python-based data extraction and Web Scraping systems that survive where others fail. Projects range from focused data extraction tasks to large-scale Anti-Bot resilient infrastructures — each engineered for stability, performance, and long-term reliability. Over 12+ years, I’ve designed extraction systems processing 1B+ structured records across marketplaces, aggregators, AI/ML platforms, competitive intelligence systems, and enterprise catalogs. My systems are built using Python, Scrapy, Playwright, and Selenium — combining Web Scraper development, Data Mining, API Integration, and ETL pipeline design into stable, production-grade architectures. Whether you need a targeted scraping solution or a high-volume distributed pipeline, I architect the right system. When data becomes mission-critical — reliability matters more than code. ────────────── What I Build ────────────── • Custom Python Web Scraper and Data Extraction systems aligned with business logic • Scalable web crawlers handling anything from selective datasets to millions of pages • Continuous update pipelines (batch & incremental ETL workflows) • Queue-based distributed processing • High-concurrency execution models • API-based data extraction and system integrations • Clean ingestion into PostgreSQL / MySQL / APIs / cloud storage • Automated validation, deduplication & anomaly detection • Structured Data Mining pipelines for growing datasets You receive structured, business-ready datasets — not scripts to babysit. ────────────── Anti-Bot & Protection Layers ────────────── Modern platforms are protected.I work inside environments guarded by: - Cloudflare (403 / 429 / Turnstile) - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - Reverse engineering of detection vectors & TLS/JA3 fingerprint alignment - Headless & browser fingerprint detection - hCaptcha / reCAPTCHA v3 Enterprise - Sustainable session & token lifecycle management This is not proxy swapping. This is controlled, sustainable access engineering. ────────────── Scale & Cost Control ────────────── As volume increases, scraping typically fails in two ways: 1) Stability collapses 2) Infrastructure & proxy costs explode I optimize concurrency models, routing logic, batching strategy, request distribution, and traffic patterns to maintain high throughput with controlled infrastructure load. Where relevant, I reduce proxy and infrastructure costs by up to 30% while preserving system stability. Result: High uptime. Predictable performance. Controlled margins. ────────────── Future-Proofing ────────────── Websites evolve. Structures change. Protection layers update. I implement structural drift monitoring and heartbeat systems that detect site changes before pipelines fail — shifting from reactive recovery to proactive control. Most developers fix scraping after it breaks. I design systems that minimize breakage from the start. ────────────── Who This Is For ────────────── • Founders building data-driven products • AI/ML teams requiring proprietary datasets • Businesses automating competitive intelligence or market tracking • Companies where reliable data access supports growth ────────────── Confidence Check ────────────── If needed, I can provide a working sample before full engagement to demonstrate data quality and bypass stability. To get started, send: - Target website(s) - Required data fields - Expected volume - Update frequency - Preferred output format Whether you're starting with a focused scraping task or building a large-scale data infrastructure — let’s build it properly.
